The capability of generating graphical images on a line printer is very desirable. Many ad hoc special purpose implementations exist that satisfy the needs of particular users. A single general purpose line printer graphics capability, however, compatible with widely distributed Calcomp pen plotter software, could eliminate the need for many special purpose implementations. An implementation approach is described for a set of subroutines which are designed to minimize storage requirements to maintain a complete graphical image. The software has been widely accepted in university, government, and industry environments to augment and occasionally replace pen plotting facilities.
